Geoshield develops window films using nano-ceramic technologies that allow for high optical clarity and energy rejection from solar control films. Their Pronano films fuse nano-ceramic particles with polyester to deliver heat rejection and aesthetics. Pronano films can block up to 76% of infrared heat from entering vehicles. Geoshield also offers Pro Classic dyed films and Geo ceramic films produced using sputtering technology to provide heat rejection and low reflectivity.
